Holotype Specimen Label

Known only from the type material, a worker found in a Philippine fern plant passing through US plant quarantine, Honolulu.


Bolton (2000) - A member of the signeae complex in the Strumigenys godeffroyi-group. Known only from the holotype, intercepted in quarantine in Hawaii, on a plant that originated in the Philippines. Pilosity on the dorsal alitrunk of the holotype is apparently abraded and some hairs may have been lost. The species appears to be closely related to Strumigenys rofocala and its allies; see comment under that name and also under Strumigenys signeae.

Bolton (2000) - TL 2.1, HL 0.56, HW 0.40, CI 71, ML 0.26, MI 46, SL 0.34, SI 85, PW 0.24, AL 0.56. Characters of signeae complex. Pilosity of dorsolateral margin of head consists of an uninterrupted series of anteriorly curved small hairs; without an apicoscrobal hair and without projecting hairs posterior to level of apex of scrobe. Apical antennomere constricted basally, only narrowly articulated to preapical segment. Cephalic dorsum with elevated short ground-pilosity that gradually increases in length posteriorly, but without obviously longer, stouter standing hairs either at occipital margin or anterior to this. Pronotal humeral hair stiff and minutely looped at the apex. Pronotal dorsum otherwise with a single pair of short erect hairs; mesonotum with 1-2 pairs of similar erect hairs. Pronotal dorsum smooth and shining; mesonotum anteriorly feebly sculptured, posteriorly rather more strongly so. Side of alitrunk with pleurae and propodeum smooth, shining and highly polished. With alitrunk in profile the propodeal teeth depressed, following the line of the propodeal dorsum rather than elevated away from it. Lamella on propodeal declivity broad, its posterior (free) margin straight-edged. With petiole in profile lateral spongiform lobe small, confined to posterior half of node. Disc of postpetiole smooth. First gastral tergite with most standing hairs simple, but some looped apically.
